SHAFT-SU PPORT.

SPECIFICATION forming part of Letters Patent No. 427,586, dated May 13, 1890.

Application led February 19, 1890. Serial No. 341,077. (No model.)

To all whom t may concern:

Be it known that we, ARICK LOTSTROM and CARL M. BIoRsErH, citizens of the United States, residing at Superior, in the county of Douglas and State of Visconsin, have invented a new and useful Shaft-Support, of which the following is a specification.

The invention relates to improvements in shaft-supports.

The object of the present invention is to provide a simple and inexpensive shaft-sup port adapted to be readily secured in place, and capable of being folded and retained in a small space and out of the way when not in use.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a shaft-support constructed in accordance with the inventionand shown applied in operative position. Fig. 2 is a side elevation of the crossbar of a pair of shafts or thills, the support being shown in its folded position. Fig. 3 is a longitudinal sectional view of the support. Fig. 4t is a detail view of the upper end of the support.

Referring to the accompanying drawings, 1 designates a shaft or th-ill support, which is constructed of metal and composed of sections 2 and 3, that are hinged together and are adapted to be locked in their open or operative position by a gravitydatch 4, which consists of a bolt 5, that is housed in a groove G and is adapted to engage a similar groove 7, and a headed pin 8, that operates in a longitudinal slot 9, communicating with a groove G when thesections align and are in operative position. The grooves 6 and 7 register and the bolt is adapted to beinserted in the groove '7 and securely lock the sections of the sup- The lower end 10 of the section 3 is pointed and adapted to engage the ground or floor of the stable and prevent the support or brace slipping. The upper end of the section 3 is provided with an integral eye lli, and is designed to be secured to the lower face of the cross bar 12 of a pair of shafts or thills at a point 15 are controlled by a threaded collar 16, that engages a threaded portion 17 of the section 2, and is adapted to compress the rubber rings or washers 15 against the crossbar 12 and prevent the support or brace slipping or moving on the loop 13, and thereby form practically a rigid connection between the crossbar and the supports. The rubber rings or washers 15, besides serving to prevent movement of the brace or support, act as antirattlers, and when the sections are folded prevent them knocking together and against the cross-bar. The cross-bar is provided near each end with a depending hook 18, that is adapted to receive the hinged ends of the sections and support the same and hold them beneath the cross-bar and parallel therewith, and the brace or support is adapted to be folded beneath the cross-bar on either side of its point of attachment therewith.

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will be readily understood.

Vhat we claim is- 1. A shaft-support comprising the sections hinged together, the latch engaging the sec tions and adapted to hold them in operative position, one of the sections being provided with an eye adapted to be secured to the cross-bar of a pair of shafts and the other section having its lower end pointed, substantially as described.

2. A shaftsupport comprising the sections hinged together, provided with suitable means for 'locking them in operative position and adapted to be secured to the cross-bar of a pair of shafts, the rubber rings or washers arranged at the upper end of the brace or IOO support, and a threaded collar adapted to compress the rubber rings or Washers, substantially as described. I

3. A shaft-support comprising the section 3, having its lower end pointed, the section 2, hinged to the section 3 and having a sliding bolt adapted to engage said section and hold the same in alignment with it and having its upper end provided with an eye, the rubber rings or Washers arranged upon the upper end of the section 2, and the threaded collar engaging the threaded portion of the section 2 and adapted to compress the rubber rings or Washers, substantially as and for the purpose described.

4L. The combination, with a cross-bar provided with a loop 13, secured io it intermediate of its ends, and the depending hooks arranged at each side of the loop, of the section 2, provided with an eye adapted to engage the loop 13, the section 3, hinged to the section 2 and having its lower end pointed, and means for locking the sections in operative position, said sections being adapted to fold together and be arranged in the depending hooks and be supported thereby, substantially as described. f y

A shaft-support comprising lthe sections hinged together, the latch engaging the sections and adapted to hold them in operative position, one of the sections being adapted to be secured to the cross-bar of a pair of shafts, Substantiallyas specified.

In testimony that We claim the foregoing as our own We have hereto a'HiXed our signatures in presence of two Witnesses.
